To all whom t may concern:

Be it known that I, ROBERT SUTOR REID, a British subject, residing at Ottawa, in the county of Carleton, Province of Ontario, and Dominion of Canada, have invented new and useful Improvements in Tent-Chimneys, of which the following is a speciication.

My invention, which will be hereinafter fully set forth and claimed, reference being had to the accompanying drawings, forming a part hereof, relates to devices for keeping iires under tents and providing for the immediate escape of the smoke.

The object of my invention is a chimney with fireplace for a tent, forming more or less a part of the latter, and one that is exible and portable with the same.

Figure 1 is a view of a bell tent, with part broken away, showing the interior with my improved fireplace and chimney. Fig. 2 is a view oi a rectangular tent, with part broken away, showing the interior with my improved fireplace and chimney. Fig. 3 is a diagrammatic section on line 3 3, Fig. 1, showing the chimney in cross-section- Fig. 4 is a diagrammatic section on line 4 4, Fig. 2, showing the chimney in cross-section. Fig. 5 is a vertical section on line 5V 5, Fig. 1, shown diagrammatically. Fig. 6 is a similar section showing a modification of the lower end of the chimney or replace; and Fig. 7 is a diagrammatic section of a bell tent, showing a modification of my improved chimney.

At the place in the body of the tent where the ireplace and chimney are to be located an insertion B, Figs. 1 and 5, and B,Figs. 2 and 4, of flexible non-combustible material, such as asbestos cloth, is put in, replacing the duck A or other material of which the tent is made and extending from the bottom to the top. In the bell tent this insertion B takes the shape of a gore. To the inner sides of this insertion is sewed a strip C in Figs. 1, 3, and 5, C in Figs. 2 and 4, of the same or similar non-combustible matertial, wider in the case of C, Figs. 1, 3, and 5, and narrower in the case of O', Figs. 2 and 4, in which latter the insertion B forms the angle of the tent and the strip O forms the hypotenuse of a triangle, and with the insertion B a triangular tube or i'lue 3, while O forms the two sides of a triangular tube or flue 2. The edges of this strip making joint with the insertion are set back from the edges of the latter, so as to leave a free space or margin 4 on each side. The upper end of this strip is not sewed to the gore, but formed into an independent vertical tube c and c', Figs. 1 and 2, respectively, which is passed to the exterior through a suitable opening in the insertion.' The lower part of said strip is formed into a boxlike space or iireplace C0 or O0 by adding sides c, Figs. 1 and 5, or co', Fig. 2, and allowing the strip to come straight down and stopping it short, so as to leave an opening 5 or the fireplace 6. Flanges 7 may be formed on the bottom of the sides 00 and 00', which may be pinned to the ground or otherwise secured.

More eil'ective heating may be obtained by bringing the replace C or O0 forward and inserting a separate back 8, Fig. 6, separating the fireplace from the insertion O or C', extra radiation of heat into the tent being thereby obtained.

In order to keep the upper or exterior ends of the chimney erect and distended, a stiii upper rim 9 may be formed by securing it to a metallic ring or rings. This is connected by a socket or other device to or made in one piece with a lever D, the latter iulcrumed on the tent-pole E and having a cord d tied to the end. By drawing this cord down and securing it to one of the tent-pegs e the chimney-tube is kept erect and distended, as shown in Figs. 1, 5, and 7. Another mode is shown in Fig. 2, in which a short rod D', with rim-ring, is secured to the top of the tentpole, acting as a tie-rod, while a strut E is secured to the tent-pole and to the rod D near the rim 9. The intermediate part oi the exterior chimney may be kept distended with wire rings.

A simple modification is shown in Fig. 7, consisting of a chimney or flue tube O2, having rimmed top 9 and terminating below in an inverted funnel or hood c2 for catching the smoke and passing through an insertion B2 in the tent, tube and insertion being made of flexible non-combustible material, such as asbestos cloth. This tube may be suspended by the devices shown and described, such as a lever D and cord d, as shown.

All the seams and joints connecting the asbestos cloth or other material oi a similar character employed will of course be made with asbestos thread or thread oi a similar character.

IOO

The insertion,.strips, and attachmentsother thanvrods being `flexible will readily pack With the other parts of the tent.

I claim as my invention-- 1. The combination with a tent of an insertion of lexible'non-combustible material having an opening in its upper part, a strip of similar material secured to the inner side thereof, forming a tubular space or Hue with said insertion and having its upper end formed into an independent tube continuous with saidf'flue'and passed ythrough said opening in said insertion, and Ineansof keeping said upper end distended and erect, -substantially as set forth.

` 2.'{The-combination with a tent, of 4an inv sertion extending up and down and consistingof flexiblenon-combustible material, such asasbestos cloth, and -having an opening near the top, a strip ofsimilar material secured yrto theiinner side of said insertion-ha ving'fi-tsf'joints therewith set: baclvfrom the edgesfthereofi-so as to leave a free margin on eachwside-and: said strip-forming atubular space or'fluewith saidinsertion, an independent tubular upper end continuous with said stripand with the flue andpassing through theopening in said'insertion, means of keeping-saidv tubular piece distended and erect, and sides of similar material insertedbetween said insertion and the edges of said strip near the lower end thereof to form a box-like space of larger capacity than the Hue, substantially as setforth.

3. rIhe-.combination with a tent, of an insertion extending up and down and consistingI of exible non-combustible material, such as yasbestosA cloth and having an opening near the top, a stri of similar material secured Ito lthe inner side of said insertion having its joints .therewith set back fromthe edges thereof so as 'to leave a free margin on each side and said strip forming a tubular space-or Hue with said insertion terminating at said opening-near the top and the lower end of said strip enlarged to cover a box-,like space forming a fireplace, substantially as set forth.

f 4. The 4combination with a tent, of an insertion extending up and down and consisting v,of flexible non-combustible material, such as asbestos cloth, and having ,an open# ing near the top, a strip of similar material secured vto the'inner side of said insertion having its joints therewith set. back -from the edges .thereof so as to leave a free margin on each side and said strip forming a tubular space or flue with said insertion terminating lat said opening near the top, and the lower end of said strip enlarged to cover a box-like 4space forming a replace, a vertical tube of similarmaterial forming an external :continuation of said flue, a lever fulcrunied on the tent-pole andhaving at one end a ring secured to the rim of said tube and keeping the same distended and a cord on said lever, silbstantially as set forth.
